| Abstract: | The flux-line lattice (FLL) has been observed on the (001) face of high Tc Bi2.2Sr2CaCu2OX and Ti2Ba2CaCu2OX single cristals using the technique of decorating the sample with small ferromagnetic particles. Strong pinning of the Abrikosov vortices by plane defects along (100) and (010) planes has been found out on Bi2.2Sr2CaCu2OX. The triangular FLL with a long-range order has been observed on the perfect Ti2Ba2CaCu2OX single crystal. The penetration depth for a magnetic field parallel to (001) axis has been evaluated as ≤0.2μm at 4.2K for both materials. |
